DETAILED DESCRIPTION

Reference will now be made in detail to examples of inventive aspects ofthe present disclosure which are illustrated in the accompanyingdrawings. Wherever possible, the same reference numbers will be usedthroughout the drawings to refer to the same or like parts.

According to the present disclosure, a telecommunications chassisconfigured to house telecommunications equipment in a high densityarrangement is provided. As will be discussed in further detail below,the telecommunications chassis is configured with cable managementfeatures for managing cables extending to and/or from thetelecommunications equipment. In addition, the telecommunicationschassis is configured to allow access to all major components of theequipment.

Referring now to FIGS. 1-7, a first embodiment of a telecommunicationschassis 10 having features that are examples of inventive aspects inaccordance with the principles of the present disclosure is illustrated.Another embodiment of a telecommunications chassis 100 includingfeatures similar to the first embodiment 10 is shown in FIGS. 8-11.

Referring to FIGS. 1-7, the telecommunications chassis 10 defines a top12, a bottom 14, a front side 16, a rear side 18, a right side 20, and aleft side 22. The chassis 10 is configured to removably receive andhouse telecommunications equipment in a stacked arrangement, wherein thetelecommunications equipment are generally stacked in a direction fromtop 12 to bottom 14.

The depicted chassis 10 includes eight panels 24, each includingreceptacles 26 for receiving the telecommunications equipment. In thedepicted embodiment, each panel 24 includes two columns of receptacles26 extending in a direction from top 12 to bottom 14. Two of the panels24 define front faces 28 that are exposed toward the right side 20, twoof the panels 24 define front faces 28 that are exposed toward the leftside 22, two of the panels 24 define front faces 28 that are exposedtoward to the front side 16, and two of the panels 24 define front faces28 that are exposed toward the rear side 18.

According to example embodiments, the types of telecommunicationsequipment that may be mounted to the chassis 10 may be removable,modular type equipment. Such equipment may include electrical equipmentsuch as digital cross-connect jack modules or cassettes. Such modulesmay include jacks having RJ-45 profiles, including Cat-5e jacks, or10-Gig jacks as known in the art. The jack modules may define connectionlocations (e.g., ports) at the fronts of the modules and connectionlocations at the rears of the modules.

In the depicted embodiment, each panel 24 of the chassis 10 isconfigured with twenty receptacles 26 (two columns of ten receptacles26) for holding twenty modules or cassettes. Thus, in the depictedembodiment, the chassis 10 has the capacity to hold one hundred sixtymodules or cassettes, forty at each side (or quadrant) 16, 18, 20, 22 ofthe chassis 10. Other numbers are possible.

As shown in the diagrammatic view in FIG. 5, each of the panels 24 thatmake up the pair of panels 24 of a given side or quadrant 16, 18, 20, 22is configured to pivotably move away from the other panel 24 of thepair. As shown in FIG. 5, the panels 24 are configured to pivot aboutpivot axes 30. By pivoting a desired panel 24, a technician is able togain access to components such as connection locations oftelecommunications equipment that are located at the rears of theequipment (and at the rear faces 32 of the panels 24) and that otherwisewould not be accessible from a peripheral exterior of the chassis 10.

As shown in FIGS. 1-7, the chassis 10 defines a central opening 34extending therethrough in a direction from the top 12 of the chassis 10toward the bottom 14 of the chassis 10. The central opening 34 isconfigured to accommodate cables that extend to and/or from thecomponents at the rears of the equipment. As noted above, by pivoting adesired panel 24 about a pivot axis 30, components or connectionlocations of telecommunications equipment that are otherwise onlyaccessible from the rear face 32 of a panel 24, the central opening 34,and any cabling therewithin may be accessed.

As illustrated in FIG. 6, the chassis 10 is configured such that it canbe rotated about a longitudinal axis 36 extending through the center ofthe opening 34. According to one example embodiment, the chassis 10 isrotatable 90 degrees in a clockwise direction. In such an embodiment, atechnician standing at the front side 16 of the chassis 10 (facing thefront faces 28 of the panels 24 at the front side 16) can rotate thechassis 90 degrees in a clockwise direction to access the front faces 28of panels 24 that are normally positioned on the right side 20 of thechassis 10. Similarly, a technician standing at the rear side 18 of thechassis 10 (facing the front faces 28 of the panels 24 at the rear side18) can rotate the chassis 90 degrees in a clockwise direction to accessthe front faces 28 of panels 24 that are normally positioned on the leftside 22 of the chassis 10. In this manner, if multiple chassis, similarto chassis 10 of FIGS. 1-7, are located in a telecommunicationsenvironment such as a data center, aisles only at the front 16 and theback 18 of the chassis 10 need to be provided and full access to allsides 16, 18, 20, 22 of the chassis 10 are provided by the rotationalarrangement of the chassis 10. The rotational arrangement also keeps anycables extending to and/or from the mounted telecommunications equipmentgenerally close to the center of the chassis 10, limiting the need forextensive cable slack.

It should be noted that the rotational arrangement discussed above,including the angle of rotation and the direction of rotation, is simplyone example and the chassis 10 can be configured for different anglesand different freedoms of movement, depending upon the desiredconnectivity and cabling arrangement.

Still referring to FIGS. 1-7, the chassis 10 also provides for cablemanagement features around the outer periphery of the chassis 10. Eachpair of panels 24 defines a cable channel or trough 38 with an adjacentpair of panels 24 that is located generally 90 degrees therefrom. Asshown, each cable trough 38 is defined by a first sidewall 40, a secondsidewall 42, and an intermediate wall 44 that connects the firstsidewall 40 to the second sidewall 42. As shown, hinges 46 that allowthe panels 24 to pivot generally about the pivot axes 30 extend alongthe centerline 48 of the intermediate wall 44. When the panels 24 pivot,the first and second sidewalls 40, 42 move toward each other. Thespacing provided by the cable trough 38 accommodates the moving panels24.

The first and second sidewalls 40, 42 defining the cable troughs 38 aredefined by panels 24 that are located at sides (i.e., quadrants) thatare generally 90 degrees apart. For example, if the first sidewall 40defining a cable trough 38 is of a panel 24 at the front side 16 of thechassis 10, the second sidewall 42 defining the cable trough 38 is of apanel 24 that may be located at the right side 20 of the chassis 10. Incontrast, the intermediate wall 44 defining the trough 38 that extendsbetween the first sidewall 40 and the second sidewall 42 is a sharedwall. A first half 50 of the intermediate wall 44 is formed by a firstpanel 24 and the second half 52 of the intermediate wall 44 is formed byanother panel 24 that is located at a side (quadrant) that is generally90 degrees therefrom.

Cables extending from and/or to the front faces 28 of the panels 24 maybe guided through the cable troughs 38. According to one exampleembodiment, cable management structures 54 in form of cable managementrings 56 may be used at locations adjacent the troughs 38 for keepingcables organized within the troughs 38. FIG. 7 is a top view of thechassis 10 illustrating one possible positional layout for the cablemanagement rings 56. The cable management rings 56 may be attached tothe first sidewall 40 defining the trough 38, to the second sidewall 42defining the trough 38, to the intermediate wall 44 defining the trough38, or to the front faces 28 of the panels 24 adjacent the troughs 38.Other locations are certainly possible. In a preferred embodiment, eachrow of receptacles 26 is provided with a corresponding row of cablemanagement rings 56.

An example cable management ring 56 that may be suitable for use withthe chassis 10, 100 of the present disclosure is shown in isolation inFIG. 12. According to one embodiment, the cable management ring 56 shownin FIG. 12 may be manufactured out of various types of polymers. Thecable management ring 56 includes an upper half 58 that is attached at afirst end 60 to a lower half 62. Each of the upper half 58 and the lowerhalf 62 defines a transverse extension 64 (e.g. a flexible flap) at asecond end 66. The extensions 64 overlap or intermate to capture a cablepassing through the ring 56 between the upper half 58 and the lower half62. If a cable needs to be inserted into or removed from the cablemanagement ring 56, it is passed through the flexible extensions fromthe second end 66 thereof When the cable management rings 56 are mountedto telecommunications structures such as the chassis 10, 100 of thepresent disclosure, the rings 56 are generally mounted adjacent theirfirst ends 60.

It should be noted that the cable management ring 56 illustrated inFIGS. 7 and 12 and described above is only one example of a variety ofdifferent cable management structures 54 that may be used with thechassis 10, 100 of the present disclosure and other structures arepossible.

FIGS. 8-11 illustrate the second embodiment of a chassis 100 havingfeatures that are examples of inventive aspects in accordance with thepresent disclosure. The chassis 100 is similar in construction andoperation to the chassis 10 described above and shown in FIGS. 1-7. Thechassis 100 defines a slightly different overall shape than the chassis10 of FIGS. 1-7. The chassis 100 of FIGS. 8-12 defines a larger centralopening 134 and larger troughs 138 between the panels 124, defined bydeeper first and second sidewalls 140, 142.

It should be noted that, although the chassis 10, 100 of the presentdisclosure have been described and depicted herein as defining a certainheight or including a certain number of receptacles 26, 126 forreceiving equipment, the chassis 10, 100 may be configured to a varietyof equipment sizes and numbers. According to certain embodiments, thechassis 10, 100 may be manufactured in a certain height or sizedepending upon the desired connectivity application. According to otherembodiments, the chassis 10, 100 may be provided in modular form,wherein similar chassis 10, 100 may be stacked on top of each other toincrease the density of the connections. When stacked on top of eachother, each chassis 10, 100 may still be configured to rotateindividually or the stacked chassis may be provided with a lockingarrangement to have the chassis 10, 100 rotate in unison. The sameprinciples could be applied to the pivoting of the panels 24, 124.

Examples of various inventive aspects of the present disclosure havebeen described herein. It will be appreciated that modifications andequivalents of the disclosed inventive aspects are intended to beincluded within the broad scope of the present disclosure.
